BRICK-FORMING DIE.

Application filed Au ust 14, 1925 Serial No. 50,251.

This invention relates to dies for forming bricks and is more particularly adapted to a device for'bevelling the edges of the blocks ofclay after the same leave the brick making'machine' V V The purpose of bevelling the edges of a brick is to enable such bricks to be used as paving blocks and more particularly those which are to be placed in the streets or highways of ahill so as to increasethe traction of vehicles and animals passing over the blocks.

Another important object of the invention is to provide a brick forming die of the above mentioned character wherein means is provided for cutting the clay material into several bricksafter the edges thereof have been bevelled.

A still further object is to provide a brick forming die of the above mentioned character which isof such construction as to per- Init the same to be readily and easily installed on the front of any well-known type of brick making machine, the same being simple in construction, inexpensive, and furthermore adapted to the purposes for which the same is designed.

Other objects and advantages of this invention will become apparent during the course of the following description.

In the accompanying drawings forming part of this specification and in which like numerals are employed to designate like parts throughout the same I Figure 1 is a front eler ationof'the brick forming die embodying my invention;

Figure 2 is a rear elevation v Figure 3 is atop plan view;

Figure 4 is a transverse section taken approximately on line it-4 of Figure 3;

Figure 5 is a detail perspective View of the clamping means associated with the cut ting wire and f 7 Figure Gfis a detailed perspective view of a paving block wherein the edges thereof are bevelled after the same have been passed through my die. 7

In the drawings, wherein for the purpose of illustration is shown a preferred embodiment of my invention, the numeral 1 designates generally the member'comprising my brick forming die, the same being preferably a substantially rectangular shaped frame ofya suitable width, the front and rear ends of which are open.

The innerwalls of the substantially rectangular shaped frame 1 gradually converge from the rear to the front of the frame and as is clearly illustrated in Figures 3 and i of the drawings, the inner walls are slightly rounded. V In thismanner the opening of the frame gradually decreases in size from the rear to the front of the frame.

he corners of the frame are bevelled as indicated at 2 to provideseveral forming faces the purpose of which will be herein after more fully described and is shown more clearly in Figures 1, 2 and 4 of the drawings, these faces gradually increase in Width from the rear to the front of the frame.

-Forn1ed on the inner wall of the top of the frame at the intermediate portion thereof and extending from the rear to the front of the frame is the triangular shaped rib 3,

a similar rib 4 is formed on the inner wall of the intermediate portion of the bottom of'the frame and also extends from the rear to the front of the frame. These ribs are disposed in vertical alignment and also gradually increase in size from the rear to the front of the frame. The ribs cooperate with the adjacent bevelledeforming faces 2, it being understood, of course, that the ribs also form bevel forming faces.

A transversely extending cutting Wire 5 is disposed across the front face of the die and the respective ends ofthe wire are re;- ceived in suitable grooves provided therefor in the inner rear faces of the clamping members 6. The groove formed in the rear face of each of the clamping members is indicated at 7. Each, of the clamping members is provided with the openings 8 through which extend the stud bolts 9, the threaded ends of which are threaded into suitable threaded openings provided therefor in the front face ofthe top and bottom walls of the frame so that the cutting wire will be secured in a taut position across the front of the die. The purpose of the wire frame isto provide a means whereby the slab of clay which is forced through the die will be cut into two bricks; It is, of course, understood that I do not wish to limit myself to the provision of a single wire or one pair of ribs and any number of ribs or wires may be provided as is desired'for forming any number of bricks that may be desired.

Dies adapted to be advanced on the front of any well known type of brick making machine so that the bricks or the slabs of clay which are discharged from the machine in the form of blocks will be forced into the rear of the frame 1, and as the clay material passes through the frame in the direction of the arrows, the faces 2 and the ribs 3 and l will cooperate to form a bevel on the outer edges of the slab of clay as well as opposed bevels on the top and bottom of the intermediate portion of the blocks and a cutting wire to pass through the bevelled portion of the slab and cut between the opposed bevels formed in the intermediate nortions at the top and bottom of the clay material. In this manner, a pair of blocks will be formed, the edges of each block being bevelled and such a block is illustrated at A in Figure 6 of the drawings.

Ordinarily, the clay material which passes through the brick making machine is cut from the side leaving the length of the bricks the full width of the slab. With the present attachment, the bricks will be cut the same way but further apart so that when the clay material passes through my improved die, the pair of ln'icks which are discharged from the die will each be of the same size as the ordinary bricks manufactured by any well kno'wn'type of brick making machine.

By bevelling the edges of the brick in the manner as above described, abrick will be provided for use as a paving block in sheets or highways which form a hill, and the bevelled edges and the adjacent paving blocks or bricks will cooperate to increase the traction'of vehicles and of animals travelling over the surface.

The simplicity in which my improved die is constructed enables the same to be manufactured at a very low cost and may furthermore be easily and readily attached on a brick making machine of any conventional construction without necessitating any material alterations of the latter. Furthermore, a device of the above character will at all times be positive and etiicient in carrying out the purposes for which it is designed.

While I have shown the preferred embodiment of the invention, it is to be understood that minor changes coming within the field of invention claimed, may be resorted to if desired.

hat is claimed is 1. A brick forming die of the class described, comprising a substantially rectangular frameopen at its front and rear, the inner walls of the frame converging gradually toward the front, bevel forming faces arranged in the corners of the inner walls of the frame, substantially triangular shaped ribs formed on the inner walls on th'e'top'and bottom respectively in the intermediate portions therco'f, said bevel forming faces and the aforementioned ribs gradually increasingin width from the rear of the frame to the open front thereof, the

bevel forming faces and the ribs cooperating to bevel the edges of the brick material which is forced through the frame from the rear to the front thereof, said ribs forming a pair of opposed bcvels at the intermediate portion in the top and bottom faces thereof, and a cutting wire extending transversely across the front face of the fame adjacent said ribs for cutting between the opposed beveled edges formed by the ribs whereby a pair of blocks is formed, the edges of which are beveled.
